A refrigerant is delivered through a balloon that is attached to the catheter guided into the heart. The refrigerant freezes the tissue and disables unwanted heart electrical currents that cause atrial fibrillation. The delivery by a balloon is revolutionary because of the continuous line of scar tissue around the pulmonary vein to stop the currents. This method is safe and effective. It has a low risk of complications. The majority of patients have been free from atrial fibrillation at one year with a reduction in symptoms, a decrease in drug therapy, and substantial improvements in quality of life.
